CLAMP-BRACKET.

Specification of Letters Patent.

Patented Apr124, 1906.

Application filed May 23, 1905. Serial No. 261,917.

To all whom, t nwtg/ concern,.-

Be it known that I, EDWARD A. LITTs, a citizen of the United States,residing at SiouX City, in the county of Woodbury and State of Iowa,have invented certain new and useful Improvements in Clamp-Brackets, ofwhich the following is a specification.

This invention relates to a clamp-bracket designed for removablyapplying an awning to the cab-windows of locomotive-engines withoutrequiring a rod or other devices commonly employed for this purpose andwhich is easily removed and adapted to be reversed or shifted fromengineers side of the cab to the iiremans side and which is portable andcapable of being carried in a grip or other convenient manner.

For a full ldescription of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings, in which- Figure 1 is a perspective view ofan awning embodying the invention, parts being broken away to disclosethe brackets. Fig. 2 is a detail view of a clamp-bracket on a largerscale. Fig. 3 is a detail view of a slide. Figs. 11 and 5 are frontdetail views of modified forms of the bracket. Figs. 6 and 7 are detailviews of different forms of awning-clamps.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Figs. 1 and 2 show the preferred construction of the awning-clampbracket, the same consisting of the frame 1, slides 2, and clamp members3, which are pivoted at their inner ends to the respective slides 2.Each slide 2 is provided with a projection 20, transversely widened toreceive an end portion of a right and a left hand threaded rod 21. Themiddle portion 22 of the rod is enlarged and preferably formed withopenings to receive a handle to admit of the application of force whenit is required to rotate the rod to effect movel ment of the clampmembers to cause them to grip the j amb of the window or other part towhich the awning is to be fastened. A forked bracket 23, affixed to theframe 1, has its forked members embodying opposite ends of the enlargedportion 22 to hold the rod 21 against longitudinal movement.

In the modification shown in Fig: i the clamp-bracket consists of aframe 1, slides 2,

clamp members 3, and operating means therefor. The clamp members 3 arelongitudinally curved and are pivotally connected at their inner ends toslides 11, which are adjustably connected with the slides 2 by means ofset-screws 5, thereby admitting of adjusting the clamp members withreference to the main slides 2, which are primarily actuated in theoperation of the clamp. The clamp members 3 are longitudinally slotted,as shown at 6, and guide-pins 7 pass through the curved slot 6 anddirect the free ends of the clamp members when moving outward or inwardaccording as the slides are forced apart or drawn together.

As shown in Fig. 4, a single lever 8 is provided for operating the clampand is pivoted at 9 to the main frame 1, connected by means of links-10to the slides 2. Movement of the lever 8 in one direction forces theslides 5 apart and imparts a corresponding movement to the slides 4 andthe clamp members 3, pivotally connected thereto. Said clamp members, byreason of their curvature and the action of the pins 7 and slots 6 moveoutward at their outer ends, thereby unclamping the part to which thebracket or device is applied. A movement of the lever 8 in the oppositedirection draws the several slides together and results in moving theouter ends of the clamp members 3 inward, whereby the bracket or deviceis clamped, fastening it to window-jamb.

In the construction shown in Fig. 5 togglelinks 1 1 connect the slides2, and upon breaking the joint said slides are drawn together, and uponstraightening the toggle-links the said slides are forced apart, withthe result that the clamp members are forced outward at their free endsin the manner and for the purpose herein stated.

A clamp member is fitted to the upper end of the bracket or main frameand may consist of a sim le clip A, as shown in Figs. 1 and 2, or may eof the form shown in Figs. 6 and 7. In both latter forms the end of theframe 1 is recurved at 14 and is provided with either a set-screw 12, asshown in Fig. 7, or a cam-le- `ver 13, as indicated in Fig. 6. An arm 15is pivoted to the curved end 14 and is provided with a jaw 16, and acompanion jaw 17 is attached to the frame 1 for cooperation with the jaw16. The jaws 16 and 17 are closed by operating either the set-screw 12or the cam-lever 13, the latter being held in the adjusted position bymeans of teeth 18 and a co- IOO IIO

Operating pawl 19. The clamps (shown in Figs. 6 and 7) are used when theawning is rodless or has ropes only run through the hems.

An arm 24 is pivoted to the lower end of each frame 1 and is provided atits outer end with a clamp or clip 25 of any construction, either asshown in Fig. 1 or in Figs. 6 and 7. The awning 26 is provided at thetop and bottom edges with a hem in which is itted a rope, the latterbeing secured by means of the clips at the ends of the frames 1 and theouter ends of the arms 24.

Having rthus described the invention, what is claimed' as new is- 1.Means for removably attaching an awning to the ambs of an opening, thesame consisting of a pair of oblong frames, one for each jamb,laterally-operable clamps at intervals 1n the length of each frame forgripping opposite sides of the jamb, means connecting the clamps of eachframe for simultaneous operation, and means at opposite ends of theframes for detachable connection therewith ofthe awning.

2. Means for removably attaching an awning to the jambs of an opening,the same consisting of a pair of oblong frames, one for each jamb, apair of slides mounted upon each frame, a clamp having adjustableconnection with each slide, means connecting said slides forsimultaneous operation, and means at opposite ends of the frames fordetachable connection of the awning thereto.

3. In a device of the character set forth, the combination of a mainframe, oppositelydisposed clamp members, slides having said clampmembers pivotally connected thereto, other slides, means for adjustablyconnecting the two sets of slides7 and actuating means lor moving thelast-mentioned slides outward or toward each other.

4. Means for removably attaching an awning to the jambs of an opening,the same consisting of a pair of oblong frames, clamps at intervals inthe length of each frame, operating means, connections adjustablyjoining the clamps to the operating means, apivoted arm at the lower endof each frame, and awningclamps at the upper end of the frames and atthe outer ends of the pivoted arms.

5. Means for attaching an awning to the ambs of an opening, the sameconsisting of a pair of frames, each provided at its upper end with aclamp, and having at its lower end a pivoted arm provided at its outerend with an awning-clamp said frames having clamp devices intermediateof their ends consisting of upper and lower pairs of clamp members andintermediate actuating means.

6. Means for attaching an awning to the jambs of an opening, the sameconsisting of a I pair of frames, each provided at its upper end with aclamp, and having at its lower end a pivoted arm provided at its outerend with an awning-clamp said frames having clamp devices intermediateof their ends consisting of upper and lower pairs of clamp members andintermediate actuating means, the latter consisting of slides having theclamp members attached thereto, operating means, and adjustableconnections between the operating means and said slides.

ln testimony whereof I aliX my signature in presence of two witnesses.

EDWARD A. LITTS.
